[0034] Embodiment 1:

[0035] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0036] A wire and cable, comprising:

[0037] A first cable 1 is provided with four supporting components 3 outside the first cable 1 , a second cable 2 is provided inside each supporting component 3 , a protective component 4 is provided outside the supporting component 3 , and a tensile component 5 is provided outside the protective component 4 .

[0038] The first cable 1 is used for transmitting electric energy or signals.

[0039] The first cable 1 includes a plurality of first cores 11 . The first cores 11 are twisted together. A tensile wire 12 is wrapped in the center of the first core 11 . A first insulating layer 13 is wrapped outside the first core 11 .

[0040] The first wire core 11 may be made of copper metal, and the tensile wire 12 may be made of glass fiber or nylon. The first insulating layer 13 may be made of PVC material, which is used for insulating the first wire core 11. The first cable 1 may be used as a communication cable or a ground wire.

[0041] The second cable 2 includes a plurality of second cores 21 . The second cores 21 are twisted together, and the second cores 21 are wrapped with a second insulating layer 22 .

[0042] The second wire core 21 may be made of copper wire or aluminum wire, and the second insulating layer 22 may be made of PVC. The second cable 2 is used for transmitting electric energy.

[0043] The support assembly 3 includes separation sleeves 31, and the separation sleeves 31 are engaged with each other.

[0044] The separation sleeve 31 is used to absorb the pressure on the cable and maintain the shape of the cable.

[0045] A limiting protrusion 32 and a limiting groove 33 are provided on the side surface of the separation sleeve 31 , and the limiting protrusion 32 and the limiting groove 33 of two adjacent separation sleeves 31 are engaged with each other.

[0046] The separation sleeve 31 can be made of PVC or resin material and is integrally formed. The front and rear sides of the separation sleeve 31 are arc-shaped edges, and the left and right sides of the separation sleeve 31 are straight edges. The limiting protrusion 32 and the limiting groove 33 are located on the straight edge of the separation sleeve 31. The limiting protrusion 32 and the limiting groove 33 of two adjacent separation sleeves 31 are engaged with each other, which can prevent the separation sleeves 31 from sliding radially with each other.

[0047] The interior of the separation sleeve 31 is a threading cavity 34 , in which a flame retardant material 35 is provided, and the second cable 2 is wrapped by the flame retardant material 35 .

[0048] The flame retardant material 35 may be talcum powder or magnesium oxide powder. The flame retardant material 35 can fill the inner space of the separation sleeve 31, provide lubrication for the separation sleeve 31 and the second cable 2, and achieve fire resistance.

[0049] The space enclosed by the separation sleeve 31 is a second threading cavity 36 , and the first cable 1 is located in the second threading cavity 36 .

[0050] The shorter arcuate sides of the four separation sleeves 31 can form a circle, and the circular space is the second threading cavity 36. The shorter arcuate sides of the separation sleeves 31 wrap the first cable 1.

[0051] The protection component 4 includes a positioning block 42, which is located between the separation sleeves 31 and is used to limit the position of the separation sleeves 31. The separation sleeves 31 and the positioning block 42 are wrapped with a fixing layer 41 outside, and the fixing layer 41 is used to press the separation sleeves 31 and the positioning block 42 inwardly;

[0052] The positioning block 42 is made of the same material as the separation sleeve 31. After the separation sleeve 31 and the fixing layer 41 are combined, they are extended to form a circle. After the fixing layer 41 wraps the separation sleeve 31 and the fixing layer 41, an inward pressure can be applied to prevent the separation sleeve 31 and the fixing layer 41 from sliding relative to each other.

[0053] The fixing layer 41 is spirally wound around the separation sleeve 31 and the positioning block 42 .

[0054] The fixing layer 41 can be made of a long strip of aluminum foil, which is spirally wound around the separation sleeve 31 and the positioning block 42, and can reduce the interference of external signals while providing pressure.

[0055] The fixing layer 41 is wrapped with a cable insulation layer 43 , and the outer insulation component is connected to the cable insulation layer 43 .

[0056] The cable insulation layer 43 may be made of rubber or PVC material, and is used for overall insulation of the cable and protection of the fixing layer 41 .

[0057] The tensile assembly 5 includes a tensile cable 51 , which is connected to the support assembly 3 via an external insulating assembly to improve the tensile strength of the cable.

[0058] The tensile cable 51 may be a steel cable made by twisting a plurality of steel wires.

[0059] The outer insulation component includes an outer insulation layer 54 , which wraps the cable insulation layer 43 . A plurality of connecting pieces 53 are arranged on the outside of the outer insulation layer 54 . A tensile protection sleeve 52 is arranged on the head of the connecting piece 53 , and the tensile cable 51 is wrapped by the tensile protection sleeve 52 .

[0060] The outer insulating layer 54, the connecting piece 53 and the tensile protection sleeve 52 are all made of insulating materials, such as PVC, rubber, resin, etc. The tensile protection sleeve 52 wraps the tensile cable 51 to play a fixing role.

[0061] Working principle:

[0062] When the cable is subjected to tension, the tension-resistant cable 51 is first subjected to tension because the tension-resistant cable 51 is external, thereby preventing the tension from being transmitted to the first cable 1 and the second cable 2, thereby improving the tension resistance of the cable and preventing the first cable 1 and the second cable 2 from sliding relative to each other.

[0063] When the cable is subjected to pressure or impact, the pressure or impact force first contacts the cable insulation layer 43 and the outer insulation layer 54, and then is transmitted to the separation sleeve 31 through the fixing layer 41. The separation sleeve 31 is subjected to the impact. Since the limiting protrusion 32 and the limiting groove 33 are engaged with each other, the separation sleeve 31 is difficult to slide and the impact force is dispersed to all the separation sleeves 31. At the same time, the separation sleeve 31 itself is deformed to absorb the impact and avoid affecting the first cable 1 and the second cable 2 inside.

[0064] The separation sleeve 31 is used to separate the first cable 1 and the second cable 2 , and cable twisting caused by twisting of the first cable 1 and the second cable 2 can also be avoided.

[0065] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
